Answer:
Given: Segment AB || segment DE, C is the midpoint of segment DB.
Prove: ΔA CB ≅ ΔE CD
Proof: In ΔA CB and ΔE CD
C is the Mid point of B D.
BC=C D→ definition of midpoint
∠A CB= ∠ EC D→→vertical angles are congruent
∠BAC=∠DEC→→[AB║DE,so alternate angles are equal]
→→ΔA CB ≅ ΔE CD[A AS or A SA]
Option B: vertical angles are congruent
Answer:
The product that represent the fraction of the circle that is shaded should be B. 1/4*2/3
Step by step explanation:
That is because when multiplied it’s 1/6.
1/4* 2/3= 2/12
2/12 /2 = 1/6
165 -25 =140
140/7= 20.

∵It slop=-4
∴Equation is: y=-4x+b
∵Point (1,-2) in this line
(∴We can substitute x, y to 1, -2)
∴-4×1+b=-2
∴b=2
Equation: y=-4x+2
